-3y^{''}-2y^'+y=t^2+t-2e^{2t}

- 3 y^{^{''}} - 2 y^{^{'}} + y = t^{2} + t - 2 e^{2 t}

y = c_{1} e^{- t} + c_{2} e^{\frac{t}{3}} + t^{2} + 5 t + 16 + \frac{2}{15} e^{2 t}

Solution steps

- 3 y^{''} (t) - 2 y^{'} (t) + y = t^{2} + t - 2 e^{2 t}

Solve linear ODE:

y = c_{1} e^{- t} + c_{2} e^{\frac{t}{3}} + t^{2} + 5 t + 16 + \frac{2}{15} e^{2 t}

y = c_{1} e^{- t} + c_{2} e^{\frac{t}{3}} + t^{2} + 5 t + 16 + \frac{2}{15} e^{2 t}
